Reply: KLIM6 is a network traffic filtering driver that works on the NDIS layer. The reason for its installation failure is mainly related to the problem of the network adapter.

1. Enter Windows 10 Safe Mode, uninstall the previously installed kaspersky, restart the computer, and then open the Registry Editor ("Run" -- type "regedit") to find out if the following registry key exists (HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\KLIM6), as shown below. If there is, please delete it, such as PCHunter.



2. Check the drive position indicated in the figure above. If it exists, delete it: C:\WINDOWS\system32\DRIVERS\klim6.sys

3. Restart your computer

4. After restarting the computer, disconnect the network and install kaspersky. (Disconnect network: What does it mean? It is to disable "local link" (wired network card) and "wireless link" (wireless network card). If both are available, both network cards need to be disabled.

5. If the installation still has problems, extract the zip file KL_KLIM6_Drivers.rar to the C drive KL_KLIM6_Drivers folder.

Next, please try to install this klim6.sys manually according to the screenshot.





If there are no errors, please be patient. After the "Network Link" property window is restored, the klim6 driver will be installed successfully. There should be no more installation errors. If this error occurs, please follow the steps below to resolve.



Go to the C:\KL_KLIM6_Drivers\602 directory, then right-click on the klim6.inf file and select "Install". If there are no errors, the installation is successful.

Windows may have a bug that occurs when the driver with the same name is reinstalled while the installer has removed the driver file located in C:\WINDOWS\System32\DriverStore\FileRepository during installing or uninstalling. Usually the installer will search for the inf file related to the product starting with oem in the INF folder. After discovery, it will try to uninstall it from the driver repository by the command pnputil.exe -d oem*.inf, but once it is uninstalled, It cannot be reinstalled unless the file name of the driver is completely changed. This phenomenon will only appear on the Windows 10 RS1 operating system, and not everyone will meet.

Reply: I don’t think the installation failure is caused by the lack of the klim6.sys file.

In addition, klim6.inf is a configuration file that belongs to a text type file and is not an executable file.

First of all, check whether you have other anti-virus software installed on your system, as kaspersky does not allow multiple anti-virus software to be installed on the system.

Second, the system must have net framework 4.0 or net framework 4.5 installed.

Finally, make sure your installation package is complete.

If you do not have the problem listed above, then please follow the steps below:

1. Clean up the temporary directory "Start" - "Run" - "%temp%", and delete the temporary file.
2. Find out the C:\ProgramData\kaspersky installation folder, and delete the entire folder.
3. Restart your computer.
4. Disconnect the network. After installing kaspersky, restart the computer and reconnect the network.

Why disconnect the network?

This is because it will take a very long time for kaspersky to check the new version and whether the environment has a compatible problem due to antivirus software. The way to disconnect the network can skip those checks.
